The Deep Dive
If we take "a number" to represent X, then "decreased by 1" means we subtract 1 from X. Hence, the algebraic expression for the sentence is X - 1. Now, if you want to throw a little party for X, remember that on the number line, every time you decrease X by 1, it’s like moving left to the next neighbor! If X is 5, then X - 1 becomes 4, and the party is just a little more subdued!
